AIR-PURIFYING DEVICE FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Nov. 3, 1908.

To all whom it may concern:

Be it known that I, H RMAN E. VVHITING, of Palmyra, in the county of Wayne and State of New York,have invented a new and useful Improvement in Air-Purifying Devices for Automobiles, which improvement is fully set forth in the following specification and shown in the accompanying drawings.

This invention relates to certain new and useful improvements in air sifters or purifiers for automobile carbureters and it has for its objects among others to provide a simple and efficient air purifier or filter by which the dust and all extraneous matter is removed from the air before the passage of the latter into the carburcter, thus keeping all foreign matter out of the cylinders, preventing false firing and thus keeping the parts in condition for longer wear and use. 1 provide an air filter or strainer for this purpose provided with a dust-catching fluid beneath a perforated plate so that when the air laden with the dust and other foreign substances passes into the device it will impinge directly against the lluid and leave therein a large portion of the extraneous matter carried by such air so that only a remnant of the dust is caught by the filtering tibcr or material within the inner chamber. This prevents the filtering material from becoming too quickly clogged with dust and hence longer runs may be made with the machine.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanyingdrawings which, with the numerals of reference marked thereon, form a part. of this in vcntion. and in which Figure 1 a diagramnlatic view with portions broken away and parts in section showing thc application of my present invention.

Fig. 2 is a perspective view of the air purifier or strainer. Fig. 3 is a substantially central vertical section on the line 33 of Fig. 4,.

Fig. 4- is a top plan. Fig. 5 is a perspective I \'l(\\' of the dcvlcc with the casing and boti tom plate rcn'iovcd. Fig. is a ('l'()5\' -{i on the line (3-6 of Fig. 5 looking in the direction ofthe arrow. Fig. is a perspective view of the regulating plate or disk.

Like numerals of reference indicate like parts throughout the several views.

Referring to the drawings 1 designates the gas inlet pipe in this instance shown as branched, as atQ, 2, and said branches leading to the cylinders 3, 3. 4. is the feed pipe from a suitable source of supply of gasolene and leading to the float. chamber 5 containing the needle valve 6 and float 7 and operating in the usual manner. These parts and all others not herein specifically described may be of any of the well known or approved forms of construction, and unless specifically mentioned in the claims form no part of the present invention.

My present invention pertains particularly to the air purifier or strainer designated as a whole by the numeral 8. v

9 is a pipe through which the purified air passes, downward through the elbow l0 and pipe 11 to the carburetor which latter, is of known construction. The pipe 11 in this instance is provided with the elbow 12 from which rises the pipe 13 within which is the chamber 14 which is contracted near its middle, being tapered in opposite directions fron'i such point of contraction, as seen clearly in Fig. 1.

15 isthe sp ay plug leading from the float chamber, as shown in Fig. l. the pipe Qbeing substantially one and ahal'l times in cross section the area of the reduced passage in this chamber through which the spray passes. From the pipe 11 extends the pipe 16 which is shown as connected with the coupling 17 leading to an auxiliary air inlet. this pipc.

however, may be omitted without in any wise affecting the operation or advantages of the present invention. it is thought that the bore is sutticicnt to enable one to understand the application of the invention. a dctailcd description of which will now be given.

The air tiltcr or strainer comprises :1 casing 18 having a floor or bottom circular plate 19 having lugs 20 for the reception of vertial bolts 31 which pass thcretln'ough and provided w th heads or the like engaging the undcrsidc of said lugs. the upper ends of said bolts passing through openings in the lugs or cars 23 on the cover or top plate 24 and receiving the thumb nuts 25, as seen best in Fig. 2. By this means the parts are firmly secured together, the top and bottom plates having annular grooves 26 and 27 respectively, as seen bestin Fig. 3, into which the inwardly extending end portions 28 and 29 of the casing fit so as to form tight joints.

The top plate Bet is provided with a plurality of openings, in this instance three as shown at 30, and depending from this top plate in line with and communicating with said openings are the depending tubes-or pipes 31. These tubes or pipes extend through and are connected with the chamber 32, the top of which is disposed at a distance from the underside of the topplate, as seen best in Fig. 5, to ,leave a space 33 therebetween, for a purpose which will be hereinafter made apparent. The bottom 34 of this chamber is provided with perforations 35 and the top 36 is provided with perforations 37 which are materially smaller than the perforations of the lower plate, as seen best in Fig. 3. This lower plate34= is disconnected and removable from the surrounding wall of the chamber, being fitted snugly over the lower ends of the tubes or pipes 31, and is held-firmly in place by means of a stiff spiral spring 38 which bears upward thereagainst and against the bottom plate 19 so as to keep this lower perforated plate of the fiber chamber firmly pressed up into place, doing away with screws or other extraneous means for holding the parts in place and allowing of ready separation of the parts when it is desired to clean the chamber or to renew the fiber or filtering material therein. This filtering. material 39 maybe of cotton or wool fiber, sponge or any other suitable material that will filter the air so as to remove therefrom the dust or other foreign substances. VVit-hin the chamber 40 interposed between the lower perforated plate and the bottom plate 19 I may place glycerin, an oil, or any viscous fluid or suitable material that evaporates slowly and serves to catch or retain the dust or extraneous matter in the air so that but a small portion of such extraneous matter is carried to the filtering material.

Within the inner chamber is the central or coaxial tube 42, as seen clearly in Figs. 3 and 6, and with which the pipe 9 communicates. Any suitable form of connection between hese pipes may be employed that will give an air tight joint. One convenient form is seen in Fig. 3.

The openings 30 in the top plate through which the air is admitted are regulated by a movable plate 43, shown detached in Fig. 7 and having openings 44: corresponding in number to those in the top plate. This movable'plate 43 is provided with a central opening 45 which receives the bolt 46 secured. centrally to the top plate, a suitable s ring 47 being provided around such bolt an the latter provided with a nut 48 by which tension on the spring may be regulated, the spring serving to moderately press the movable plate a ainst the top plate, as will be und'erstood From Fig. 2. This movable plate is provided with a lateral lug 49 having an opening 50 for attachment to an arm or lever 51 by means of which the said plate may be rotated to regulate the size of the intake openings.

The operation will be readily understood z-The atmospheric air carrying dust and other extraneous matter or substances passes in through the intake openings 30 wardly through the tubes 31 into the chamber 40. The air in its downward passage impinges directly against the glycerin or other dust-catching fluid, leaving in the latter a large portion of the, extraneous matter carried by such air so that only a very small remnant of the dust remains to be caught by the filtering fiber or material in the inner chamber. This will prevent the. fiber from too quickly becoming clogged with the dust so that the life thereof is materially lengthened and much longer runs may be made with the auto. The air thence passes up through the lowermost perforations and through the body of the dust-catching fiber and through. the'smaller perforations at the top of the fiber chamber, and thence again downward through the main'central tube 42, through the elbow 10, pipe 11, elbow 1.2 and contracted chamber 14: to the carbureter. By removing the thumb nuts 25, the top plate, the controller plate and the parts. carried thereby may all be bodilyremoved, as seen in Fig. 5, when the bottom plate 34 can be easily removed, to provide access to the inner chamber so that the filtering fiber therein may be removed and new fiber put in its place.

Modifications may be resorted to withou departing from the spirit of the invention or sacrificing any of its advantages.
